This paper studies the dynamic event-triggered output feedback control problem for networked switched systems (NSSs) under communications consisting of network congestion and data collisions. A dynamic event-triggered mechanism (ETM) is constructed in the sensor-controller network channel, which reduces unnecessary communications and saves network resources. To prevent data collisions in the controller-actuator network channel, the Round-Robin protocol (RRP) is used for communication scheduling, where a periodic function is used to select nodes gaining access to the network. Under the dynamic ETM and RRP, a dynamic output feedback controller is designed, and sufficient conditions are derived to ensure the mean square exponential stability (MSES) of the underlying NSSs using the mode-dependent average dwell time (MDADT) approach and multiple Lyapunov function techniques. Switching-mode-dependent controllers are further derived to achieve the desired stability. Finally, an application oriented example of F-18 aircraft model is provided to verify the usefulness of the proposed theoretical results.
